captioning sponsored by cbs this is the "cbs evening news" reporting live tonight from newtown. >> axelrod: good evening. newtown, connecticut was, by many measures, one of the safest communities in america. it is now the grief-stricken home of the second deadliest school shooting in u.s. history. 28 people are dead, including the shooter. late today, connecticut's chief medical examiner, wayne carver, reported that the autopsies on all the children are now complete. all 20 of them were shot more than once by 20-year-old adam lanza. police have also released the names of those killed, eight boys, 12 girls, between the ages of 6 and 7. all were first graders. six adults at the school were also murdered, and investigators say they now have some very good evidence explaining what wasde .

we have a team of cbs news correspondents and producers on this still-developing story. we begin with margaret brennan here in newtown. >> reporter: gflg, jim. and the bodies of those 12 girls, eight boys, and six adult women killed right here in the sandy hook shooting yesterday are being returned to their families tonight, more than 24 hour after the brutal mass

six-year-old emilie parker and jesse lewis. tomorrow, the medical examiner will conduct autopsies on adam lanza and his mother. and the families will begin the process of laying their loved ones to rest. jim. >> axelrod: margaret, thank you. it is still unclear what if any connection the gunman's mother had to the school. but we do know the weapons adam lanza used to kill his victims came from her home. bob orr is in washington with more on the investigation. good evening, bob. >> reporter: good evening, jim. as new details emerge, the scope

of the horror explains. gunman adam lanza apparently sprayed two classrooms at sandy hook elementary school with relentless fire from a semiautomatic assault rifle. it was a massacre, and most of the victims were first graders. autopsies on the bodies of the children revealed that many, if not all, had been shot multiple times. wayne carver is the chief medical examiner for connecticut. >> i only did seven of the autopsies. the victims i had ranged from 3 to 11 wounds apiece and i only saw two of them with close-range shooting. >> reporter: investigators believe most of the bullets came from a bushmaster 223 assault rifle. it was one of four guns adam lanza took from the home he shared with his mother after he shot and killed her. sources say he left one gun in his car and then forced his way into the school, carrying the assault rifle in his hands and two semiautomatic pistols in the dark military-style cargo pants

he was wearing. inside the school, he zeroed in on two classrooms, killing the 20 children and six adults. one of them was the school's principal, who sources say tried to stop the shooting by lunging at the gunman. the spree ended when lanza shot himself with one of the handguns. police have yet to find any journal or detailed notes lanza may have left behind explaining his horrific actions. but lieutenant paul vance said clues to the possible motive have been recovered in multiple searches. >> did produce some very-- a very good evidence in this investigation, that our investigators will be able to use and hopefully painting the complete picture as to how and more importantly why this occurred. >> reporter: now, we have to say it's not clear why at this hour lanza targeted that elementary school. there were early reports yesterday indicating the mother naiive a teacher there, perhaps an aide at sandy hook.

police have found no evidence she had any obvious connection to the school. and one more thing, jim. police now are checking on a different report that maybe adam lanza was involved in an argument with staffers at the school the day before the shooting, but i have to emphasize they have not yet confirmed that. jim. >> axelrod: bob orr in washington, thank you. senior correspondent john miller has been talking to his law enforcement source. he joins me now for more. john, are you hearing anything about this altercation? >> reporter: yeah, i spoke to a senior law enforcement source this evening about that, and he said what we're focused on was there was some kind of argument between people in the office and people in the office of that school are dead today. he said the key is to figure out if lanza was part of that, present for tor somehow involved. he said right now they don't have any indication he was. but they said they have to run that out it make sure. >> axelrod: you're also learning more about the guns used in the shooting that belonged to lanza's mother? >> reporter: yeah, it's about the process, which is she had to

to go to an awful lot of trouble to get these guns. connecticut has some of the toughest gun laws in the country. that means going down to the state police, filling out the forms, get, fingerprinted and waiting to hear back that she was approved fair handgun permit, then getting an f.b.i. background check, and waiting for that period and picking the weapons up. it's not one of those things where you show up with a driver's license and make the purchase. as we learned from the landscaper, she enjoyed shooting. we spoke to another relative who also said she was worried about the defense of her home, if there was a collapse of the economy, she wanted to have weapons on hand to defend them, which,sh, only underscores the irony that those were the guns used by her own child to kill her and so many others. >> axelrod: john miller in new york, thank you. as this community comes to grips with the loss of so many lives, late today we heard from the father of one of the first graders slain yesterday.

you will always find people helping," she said. and certainly, that was the case here in newtown. jim. >> axelrod: michelle miller, thank you. will the massacre move congress to consider tougher gun laws?

that makes any kind of meaningful action, as the president put it, all but impossible, particularly at a time when he has so much else on his agenda. jim. >> axelrod: bill plante, thank you. and the politics of gun control will be the focus of a panel discussion on tomorrow's facethe nation with bob schieffer. and then there's this, in oklahoma, an 18-year-old high school student is under arrest and charged with plotting to bomb and shoot students at his school. the arrest came yesterday, the same day as the shooting here. and in chicago, 10 people were shot overnight, four of them teenagers. and we'll be back. ♪ ♪ [ male announcer ] campbell's green bean casserole. it's amazing what soup can do
